Daily Sudoku
The Daily Sudoku serves one fresh 9×9 grid each day, the same puzzle for everyone, so your time stands next to every other solver's. Sudoku is a logic placement puzzle invented in its modern form by Howard Garns in 1979 and popularized worldwide in the mid-2000s. The daily format makes it a fixed routine with a streak rather than an endless stream of random boards.
Daily Sudoku Rules
Each day a single 9×9 grid loads, pre-filled with a set of given numbers (the "givens"). The same arrangement is served to all players for that date, so it's a fair shared challenge.
Your task is to fill every empty cell with a digit from 1 to 9 so that each row, each column, and each of the nine 3×3 boxes contains all nine digits exactly once. A well-formed daily puzzle has exactly one solution reachable by logic alone.
The grid is complete when all 81 cells are filled with no repeated digit in any row, column, or box. Finishing extends your daily streak and records your solve time for comparison.
Daily Sudoku Strategy & Tips
Scan for naked singles first
Sweep the grid for cells where only one digit can legally go. On most daily puzzles a chain of these obvious placements opens the board before you need anything harder.
Pencil in candidates early
Mark the possible digits in each empty cell. The notes turn an intimidating grid into a visible logic problem and reveal hidden singles you'd otherwise miss.
Hunt pairs and triples
When two cells in a unit can only hold the same two digits, those digits are locked there and can be cleared from the rest of that row, column, or box — often the key to a stuck grid.
Solve daily to learn the rhythm
Because the daily puzzle keeps a consistent difficulty, repeating it builds technique recognition. Track your time and you'll see the same patterns fall faster each morning.
Frequently Asked Questions
Is the daily Sudoku the same for everyone?
Yes. One grid is generated per calendar date and given to every player, so your completion time is directly comparable to anyone else solving that day's puzzle.
Does every daily Sudoku have only one solution?
A proper Sudoku, including the daily, has exactly one solution that can be reached through logic without guessing. If you find yourself guessing, there's usually a deduction you missed.
How long should a daily Sudoku take?
It varies with the day's difficulty and your experience — many solvers finish in five to fifteen minutes. The daily format is built so you can chase a faster personal time.
Do I lose my streak if I skip a day?
The streak counts consecutive days you complete the puzzle, so missing a day resets it. Solving today's grid before midnight keeps the run going.
